Dried Wood vs Green Wood
OverviewBoth dried wood and green wood have merits and drawbacks, this slideshow will explain when use one or use the other.
To understand which wood to use in your work then you have to know what each type of wood is, and when it’s best to apply them.
Dried WoodTo achieve a wood product that has less than
20% moisture content, it must be seasoned or
dried. There are two processes that are used to
do this, one is air drying, and the other is kiln
dried.
Kiln dried wood is wood that is sawn, placed in a kiln and dried using warm air currents. Kiln drying is a considerably faster process to traditional air drying. This method produces a much harder product usually reserved for the building trade.
Air dried wood is pretty self-explanatory, it’s wood that has been left to dry in the air, as opposed to applying heat to dry it. It is the more traditional method of drying wood and gives the timber a little more flexibility.
Green Wood
Green wood refers to wood that has been recently cut down and has not had an opportunity to season. Seasoning refers to the drying on the internal moisture that is in the wood. Green wood is considered to have a 100% moisture content relative to air dried or seasoned wood.
Dried Wood ApplicationsKiln Dried wood is the industry standard for construction. It is the most consistent and stable product offered after the drying process.
Smaller woodworking projects, such is with chisels or on the lathe may want to consider using air dried wood, as kiln dried wood can be unforgiving and hard on tools.
Kiln dried wood offers the most efficient burning for fuel, it nearly 100% burn heat efficiency.
Air dried wood contains much less moisture than green wood, but a little bit more than the faster and more aggressive method of Kiln drying.
Air dried wood is a solid, stable medium for construction projects such as furniture, as it’s easy to work with and does not go through the kiln process, which can cause damage to the wood.

Kiln dried wood offers the most efficient burning for fuel, it nearly 100% burn heat efficiency.
To Sum Up
Green wood should only really be used if you’re trying to get a specific look or are practicing your woodworking techniques, and rarely used for fuel and structural projects.
Air dried wood can be used for construction and is a good burner, it is more forgiving on tools than kiln dried wood, so can be used for wood working projects.
Kiln dried wood is the go to for construction and fuel, although it can be unforgiving on tools so you should take caution when using it.
